Abstract

Duhok University has two main campuses. The first is the Malta campus located at the western part of the city and consists of seven colleges. The second one is the Duhok center which is located in the city center, it comprises six colleges in addition to the university chancellor office. This research paper proposes a network design for Duhok University to enable student and academic staff exchanges their academic and administrative information efficiently. The proposed IP Network design is made of three layers of which the core layer consists of two Cisco SONET 12012 which is connected by dual links. One of the SONETs is assigned to the Malta Campus and the other to Duhok center campus. The minimum spanning tree is calculated for the proposed IP network by using real distances between university colleges. At the distribution layer, a hierarchical topology is used to connect the college campus to its nearest main campus. The network is attached to the two main FTP and HTTP servers. The data stream of each college is forwarded to Cisco router 4700. The user layer in each department is implemented using star topology through a Cisco switch 2924. Mobility access is added to the proposed design to support wireless devices. The design is implemented using OPNET 14.5 modular. Network performance and server's quality are tested by calculating (packet/second), delays, traffic send, traffic receives utility, and throughput in case of heavy load the network performance and server's quality. The results show that the proposed Duhok University IP network fulfills the network requirements and future expansion

Highlights

Information technology is important to sustain the progress and facilitate task implementation in business and academic enterprises
The Minimum Spanning Tree (MST) is calculated for the proposed network based on real distances between colleges and university to minimize the costs of additional links
Duhok university campus is divided into three layers: the access, distribution and core layers respectively with the core network layer providing the backbone for the network while the distribution layer aggregates multiple technologies from the access layer

Summary

Introduction

Information technology is important to sustain the progress and facilitate task implementation in business and academic enterprises. The present research proposes an upgraded, reliable and robust design for Duhok University campus Duhok University It is possible for the model to be expanded in case of an increase in the number of colleges which eventually leads to an increase in the number of students and staff. Many kinds of research and projects have been conducted to network modeling, simulation, and verification: Junaid Ahmed Zubairi et al [2] Their proposed campus design has recently shifted to switched Ethernet subnets and Gigabit Ethernet backbone and has studied the performance of the time-sensitive applications on campus network under varying load conditions using OPNET. Ibikunle Frank et al[6]proposed a means of improving campus network performance by presenting a network model based on Multiprotocol Label Switching-Virtual Private Networks (MPLS-VPNS), a technique basically used by network service providers.
